Random UI freezing whilst in combat :(

The problem I'm getting doesn't produce any LUA errors so I can't tell what addon is causing it, but when I'm in combat, my cast bars freeze in place and I can't send any whispers or see the loot list after a boss kill. To "unfreeze" the screen, I reload the interface (/rl) and everything seems to be fine until it happens again. >.>

I have reinstalled the game and used the repair tool, but the random freezing still occurs. :<

Re: Random UI freezing whilst in combat :(

Probably 2 addons are conflicting. Unfortunately, the only way to troubleshoot this is a very long and slow method - the standard "turn half your addons off. If the problem goes away, turn half those addons back on. If it still happens, turn off half of what's left." method.
